MILK vnssnt FOR MILKiNG-MAQHINES wonxme wrrn vacuum.

To all whom it may concern Be it known that I, KNUT Ivan Linnsrnom, estate-owner, a subject of the King of Sweden, residing at Djursholm, Sweden, have invented certain new and, useful Improvements in Milk Vessels for Milking-Machines Working with Vacuum, of which the followin is a specification.

In .mili vessels for such milking machines as work with vacuum and where the milk is sucked into a collecting vessel in which a vacuum is prevailing, one has generally made use of the cover fittedpn the upper part of the vessel for emptying the mllk from the milk vessel after the milking has been performed. The chief purpose of the cover is, however, to provide, an access to the interior of the milk vessel for cleaning purposes.

- In order to facilitate the emptying of the milk from the milk vessel, also when this latter is mounted on. the cow, there is, according to the present invention provided an opening at or close to the bottom of the milk vessel which opening is closed by a cover that partly is he d pressed against the edge of the opening on account of the vacuum prevailing in the milkvessel, and partly is,

secured in position by means of lu'gs, a bayonet clutch, threads, or similar devices.

A milk vessel in accordance with the invention is shown in side view in Figure l of the annexed drawing. Figs.

Z indicates the milk conduit between the vessel and the inner chamber of the teatcup.

d is the said socket of the vessel and provlded with two projecears or lugs e engaging projections m on the cover f so as to secure this latter in position. It will be understood from the drawing that the cover f is secured and loosened by rotating it around its center. The cover f is provided with a handle g. The arrangement is such, that, when the cover is'rotated so as to cause the projections at to engage the lugs c, it is also pressed against the opening of the flanged socket d. The inner surfaces of the lugs are respectively somewhat inclined as shown in Fig. 1. During the milking proctions,

fitted near the bottom ess the cover is besides, pressed against the .opening of the socket'd on account of the ing close to the bottom of the vessel, and a cover foreach of said -openings,-"s aid vessel and'the cover for the second opening having inter-engaging members for-holdingthe same in position overjsaid, second opening, cove'r being pressed against" the mouth of said second openingdurin'g the milking process on account of the vacuum prevailing inthe vessel. r
